Stoney Slough National Wildlife Refuge is a national wildlife refuge in Barnes County, North Dakota. The nearest town is Valley City, about 24 km (15 mi) away (Stoney Slough National Wildlife Refuge lies SSW of town).
Stoney Slough National Wildlife Refuge is a 2,000-acre (810 ha) easement refuge with 1,120 acres (450 ha) owned in fee title and the remaining area of 880 acres (360 ha) covered by easement. The United States Fish and Wildlife Service fee title of 1,120 acres allows some wetland and upland management. The wetland areas on the Refuge cover approximately 600 acres (240 ha) in four permanent pools and two temporary pools. Water management using a series of canals and a water control structure is possible when there is sufficient spring runoff. The Refuge is a popular stopover for snow geese and white-fronted geese during fall migration. The refuge was established by Executive Orders during the Franklin D. Roosevelt administration and was set aside as "a refuge and breeding grounds for migratory birds and other wildlife". The refuge is maintained by the Valley City Wetland Management...From the Wikipedia article “Stoney Slough National Wildlife Refuge”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Stoney Slough National Wildlife Refuge, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.3 hours on a moonless night), and the core peaks around 14° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.89 mag/arcsec². Aurora needs roughly Kp 4.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 46% average cloud cover) and March as the cloudiest (67%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this national wildlife refuge
- A 400–600 mm lens (or a crop body) is the usual tool for birds.
- Fast shutter speeds (1/2000 s+) freeze wingbeats; raise ISO rather than lose the shot.
- Migration peaks bring the largest concentrations — see the birding calendar for this state.
- Use auto-loop roads as mobile blinds; animals often tolerate vehicles more than people on foot.
- Check road and trail conditions with the managing agency before you go.
Season: Spring and autumn migration are the highlights; winter brings waterfowl to many southern refuges.
Suggested gear: Telephoto lens (400 mm+), Bean bag for car window, Binoculars. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Launching or landing drones on National Wildlife Refuge lands generally requires a special use permit from the refuge manager, and wildlife disturbance rules apply everywhere.
